The anterior loop of the inferior alveolar nerve is a sensitive anatomical feature which should be taken into account during installing dental implants anterior to the mental foramen. Since results regarding its prevalence and length are controversial, this study was conducted. A total of 452 mandible quadrants of 234 patients (age: 50.1±13.3 years, 113 males, 121 females) were studied using cone-beam computerized tomography (CBCT). After reconstructing axial, frontal, and sagittal slices, the region between the most anterior point on the mental foramen and the most anterior part of the mandibular nerve was inspected for signs of anterior loop presence...

The aim of this study was to assess the effect of DLC (Diamond-like carbon) coating on the removal torque of prefabricated implant screws after cyclic loading. Four groups with two crowns supported by two implants (n=5) were obtained according to splinted and non-splinted prosthesis, using titanium or DLC screw (STi, SC, NSTi and NSC). The prosthetic screws were tightened at 32Ncm, retightened, and the specimens were submitted to 106 mechanical cycles (4Hz/98N). After cyclic loading, loosening torque was evaluated and the final measurements were performed...

GBR is a technique sensitive procedure that routinely involves placement of particulate bone with or without fixation screws and either a resorbable or a non-resorbable membrane. Grafting of the buccal-crestal aspect of the implant site can be particularly challenging as external pressure from the flap or occlusal forces may displace the graft laterally and apically resulting in deficient bone in the desired region. A novel technique for stabilizing a resorbable membrane and underlying particulate graft allowing for predictable bone grafting across multiple edentulous sites...

The objective of this research was to clinically compare peri-implant tissue health of bar-clips versus silicone-resilient liners used with bilateral posterior bars for retaining four implant supported mandibular overdentures. Thirty completely edentulous male patients (mean age 65) were randomly assigned into two equal groups. Each patient received four implants in canine and first molar regions of the mandible using flapless surgical technique. Mandibular overdentures were immediately connected to the implants with bilateral prefabricated instant adjusting bars...

There is controversy in the literature regarding the indicated retentive mechanism for implant supported crowns. When adjacent implants are restored, the restoration can be either screw retained, cement retained, or a combination of cement and screw retained. Adjacent implant supported crowns can be restored as individual implant supported crowns or they can be splinted. A classification system is proposed when adjacent implants are restored. The classification system describes currently available options to restore adjacent implants...

Many dental procedures allow for implant placement in partially or totally edentulous patients. Despite the availability of various implant and abutment types on the market, it often becomes quite challenging to achieve the biological and esthetic goals in a patient who has ridge deficiencies. Where problems will arise is from the lack of adequate bone quality and quantity.1,2 Soft tissue form and maintenance is also a consideration to evaluate.3 Primary reconstructive techniques following segmental mandibulectomy is evolving and improves quality of life...

The lack of compatible prosthetic components can be a complication during oral rehabilitations using outdated implants. The aim of the present clinical report was to describe an alternative technique for the fabrication of a maxillary implant-supported overdenture in a patient with 20-year-old dental implants using castable spherical patterns and ball-attachments. The patient had been wearing a relined bar/clip overdenture in the mandible on four external-hexagon dental implants and a relined complete denture in the maxilla on four internal-hexagon implants due to abutment screw fracture inside of the implants, losing the attachment system...

We evaluated the effectiveness of the open membrane technique using a high-density polytetrafluoroethylene (dPTFE) membrane with freeze-dried bone allografts (FDBA) in damaged sockets for alveolar ridge preservation (ARP). This retrospective study included 26 sites from 20 patients who had received ARP for the placement of dental implants. ARP was conducted using dPTFE membrane with allografts on the day of extraction without primary closure. When the membrane was removed after 4 weeks, the newly-formed reddish tissue at the grafted site was checked (1st outcome, clinical evaluation)...

The procedure of crestal maxillary sinus floor elevation presents a great challenge to the field of implant dentistry. Due to the limited visualization in this procedure, the effectiveness of detaching sinus mucosa could not be assessed in real time. We recently developed an ex vivo goat sinus model by cutting the goat residual skulls along four lines determined from computerized tomography (CT) scans, extracting the maxillary pre-molar or molar teeth, and preparing implant socket in the maxilla. The generated ex vivo goat sinus models exposed the maxilla and the whole maxillary sinus mucosa, thus enabling real time observation of detaching maxillary sinus mucosa via directly visualizing the working situation of sinus lift tool in the models, and directly measuring the length of detached mucosa and the space volume generated under the elevated sinus mucosa...

Numerous grafting materials have been used to augment the maxillary sinus floor for long-term stability and success for implant-supported prosthesis. To enhance bone formation, adjunctive blood-born growth factor sources have gained popularity during the recent years. The present study compared the use of platelet-rich fibrin (PRF) and bovine-autogenous bone mixture for maxillary sinus floor elevation. A split-face model was used to apply 2 different filling materials for maxillary sinus floor elevation in 22 healthy adult sheep...

Horizontal ridge augmentation with allografts has attracted notable attention because of its proper success rate and the lack of disadvantages of autografts. Corticocancellous block allografts have not been adequately studied in humans. Therefore, this study clinically and histomorphometrically evaluated the increase in ridge width after horizontal ridge augmentation using corticocancellous block allografts as well as implant success after 12 to 18 months after implantation. In 10 patients receiving implants (3 women, 7 men; mean age = 45 years), defective maxillary alveolar ridges were horizontally augmented using freeze-dried bone allograft blocks...

This study tested the fracture strength of prosthetic abutments with different sizes and combinations to support a 5-implant milled framework with distal extension. Prosthetic abutments with different dimensions (4.8-mm diameter mini conical abutment and 3.5-mm diameter microconical abutment) were screwed to 5 threaded implants. The following groups were divided (n = 3): G1 with 5 miniconical abutments (standard size), G2 with 5 microconical abutments (small sized), G3 with a combination of 3 small sized abutments and 2 standard sized abutments, and G4 with a combination of 2 small sized abutments and 3 standard sized abutments...

For decades titanium has been the preferred material for dental implant fabrication, with mechanical and biological performance resulting in high clinical success rates. These have been further enhanced by incremental development of surface modifications aimed at improving speed and degree of osseointegration and resulting in enhanced clinical treatment options and outcomes. However, increasing demand for metal-free dental restorations has also led to the development of ceramic-based dental implants, such as zirconia...
